. A guide to the study of fishes. Fishes; Zoology; Fishes. 4o8 The Squamipinnes fish, lancet-fish, tang, barbero, etc., and it forms a very effective weapon against fish or man who would seize one of these creatures by the tail. The species have the center of distribution in the East Indies and have not reached Europe. Three species are found in the West Indies. The blue tang {Teuthis cceruleus) is chiefly bright blue. The common tang, Teuthis chirurgus, is brown with bluish streaks, while a third species, Teuthis bahi- anus, has a forked caudal fin. Very close to this species is Teuthis crcstouis, of the west coast of ]\Iexico, and both are closely related to TcntJiis matoides, found from India to Hawaii. Teuthis triostcgus, of Japan and Polynesia and the East Indies, is covered with cross-bands alternately black and Fig. .344.—Brown Tang, Teuthis bahianus (Ranzani). Tortugas, Fla. In Hawaii this is replaced by the very similar Teuthis saud- wichensis. Many species are found about Hawaii and the other Polynesian Islands. Teuthis achilles has a large blotch of bril- liant scarlet on the tail, and Teuthis olivaceus a bright-colored mark on the shoulder. Teuthis liucatus, yellow with blue stripes, a showily colored fish of the coral reefs, is often poison- ous, its flesh producing ciguatera. Zebrasoma differs from Teuthis in having but 4 or 5 dorsal spines instead of 10 or 11. In this genus the soft dorsal fin is very high. Zebrasoma flavescens, sometimes brown, sometimes bright.
